Suggest three uses for a rewards based credit card.

assistant
1. Earning rewards: A rewards based credit card allows you to earn and accumulate points as you make purchases with your card. The points can then be exchanged for cash, gift cards, and other rewards. 
2. Financial flexibility: A rewards based credit card can provide extra financial flexibility, allowing you to make purchases that you wouldn't be able to afford otherwise. 
3. 0% introductory APR: Some rewards based credit cards offer a 0% introductory APR (Annual Percentage Rate) which can be beneficial if you need to make a large purchase and take some time to pay it off.
